gpu/drm/drm_gem_shmem_helper.c

30  * This library provides helpers for GEM objects backed by shmem buffers
33  * Functions that operate on the GEM object receive struct &drm_gem_shmem_object.
34  * For GEM callback helpers in struct &drm_gem_object functions, see likewise
118  * This function creates a shmem GEM object.
131  * drm_gem_shmem_free - Free resources associated with a shmem GEM object
132  * @shmem: shmem GEM object to free
134  * This function cleans up the GEM object state and frees the memory used to
201  * drm_gem_shmem_put_pages - Decrease use count on the backing pages for a shmem GEM object
202  * @shmem: shmem GEM object
253  * drm_gem_shmem_pin - Pin backing pages for a shmem GEM object
254  * @shmem: shmem GEM object
280  * drm_gem_shmem_unpin - Unpin backing pages for a shmem GEM object
281  * @shmem: shmem GEM object
299  * drm_gem_shmem_vmap - Create a virtual mapping for a shmem GEM object
300  * @shmem: shmem GEM object
301  * @map: Returns the kernel virtual address of the SHMEM GEM object's backing
305  * exists for the buffer backing the shmem GEM object. It hides the differences
369  * drm_gem_shmem_vunmap - Unmap a virtual mapping for a shmem GEM object
370  * @shmem: shmem GEM object
371  * @map: Kernel virtual address where the SHMEM GEM object was mapped
584  * drm_gem_shmem_mmap - Memory-map a shmem GEM object
585  * @shmem: shmem GEM object
588  * This function implements an augmented version of the GEM DRM file mmap
637  * @shmem: shmem GEM object
655  *                              pages for a shmem GEM object
656  * @shmem: shmem GEM object
716  *				 scatter/gather table for a shmem GEM object.
717  * @shmem: shmem GEM object
746  * drm_gem_shmem_prime_import_sg_table - Produce a shmem GEM object from
757  * A pointer to a newly created GEM object or an ERR_PTR-encoded negative
